Technical Analysis

Detailed breakdown of GeForce 8400M G specifications and capabilities.

Graphics Performance

The GeForce 8400M G scores 105 in the G3D Mark benchmark (the standard measure of rasterization GPU performance), placing it in the Entry Level tier as a Legacy generation graphics card. It is built on the Maxwell (2014−2017) architecture (codename: GM108), manufactured on a 28 nm process— smaller process nodes improve power efficiency and transistor density. It packs 384 shader units (the primary compute units for rendering pixels), 16 TMUs (texture mapping units), and 8 ROPs (render output units that handle final pixel output). Raw FP32 compute power: 0.8632 TFLOPS — this measures the theoretical peak floating-point performance. Boost clock reaches 1124 MHz from a base of 1029 MHz.
